Civil air defense engineering sealing protective door
The invention relates to a civil air defense construction sealing protective door, and belongs to the technical field of civil air defense doors, the civil air defense construction sealing protective door comprises a door frame and a door leaf arranged on the door frame, a mounting seat is arranged on the door frame, a hinge shaft is arranged on the door leaf, and the hinge shaft is rotatably arranged in the mounting seat; the hinge shaft is rotationally arranged on the door leaf, the rotating axis of the hinge shaft is perpendicular to the plane where the door leaf is located, a fan-shaped groove is formed in the mounting base, the angle of the fan-shaped groove is 90 degrees, the plane where an opening of the fan-shaped groove is located is parallel to the ground, and when the door leaf is in a closed state relative to the door frame, the plane where the fan-shaped groove is located is parallel to the plane where the door leaf is located. The hinge shaft rotates out of the mounting seat along the fan-shaped groove; a rotating piece is arranged on the door leaf and used for fixing the hinge shaft to any position after rotation; a limiting piece is arranged on the mounting base and used for limiting and fixing the hinge shaft when the hinge shaft is in the vertical state. The door has the effect of facilitating opening of the door leaf.
本申请涉及一种人防工程密封防护门，属于人防门技术领域，包括门框和设置在门框上的门扇，门框上设置有安装座，门扇上设置有铰接轴，铰接轴转动设置在安装座内；铰接轴转动设置在门扇上，铰接轴的转动轴线垂直于所在门扇的平面，安装座上开设有扇形槽，扇形槽的角度为90°，扇形槽开口所在平面平行于地面，门扇对门框呈闭合状态时，扇形槽所在平面平行于门扇所在平面，铰接轴沿扇形槽从安装座内转出；门扇上设置有转动件，转动件用于固定铰接轴至转动后的任意位置；安装座上设置有限位件，限位件用于铰接轴处于竖直状态时，对铰接轴进行限位固定。本申请具有便于门扇开启的效果。
